Abstract

A method is provided for forming an electrical conductors, comprising forming electrically conductive segments incorporating electromigration-inhibiting plugs. A row of windows is formed in a planar surface and electromigration-inhibiting material is deposited over the planar surface and into the windows to provide electromigration-inhibiting plugs in the windows. The plugs may be formed by depositing an electromigration-inhibiting liner in the windows and then depositing electrically conductive material to fill the windows. Portions of either or both of the plugs and conductive segments are removed such that the plugs and conductive segments have a coplanar surface. The plugs may be formed in windows in an electrically conductive layer defining the conductive segments. Alternatively, windows may be formed in a dielectric layer and the conductive segments formed from electrically conductive material deposited in trenches in the dielectric between neighboring windows, the plugs, conductive segments and dielectric surface being coplanar. Embodiments of the method may be employed in manufacture of integrated circuit conductors.

Important Notes on Latency of Status data

Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.

An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.

A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.

An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
